I don't have an exact count, but there are a fair number of drawbar samples from Helios (under names like KW Drawbar, etc.) for Klaus W. type sounds. There are also samples from the CD (Spectra) series for both drawbars and a few strings if I recall. The attached list is a little dated. With the recent updates to OAX 2.0, they renamed some of the sounds and also replaced some of them with newer samples.
